According to preliminary national estimates from Nielsen, ”Big Brother” averaged a big 2.8 rating/9 share in adults 18-49 and 8.1 million viewers overall in the 8 o’clock hour Sunday, dominating its timeslot and rising 12% week to week. Also for the Eye, ”60 Minutes” (1.3/5 in 18-49, 8.8 million viewers overall) gained vs. last week as well, while 9 p.m. newcomer ”Same Name” (1.4/4 in 18-49, 4.4 million viewers overall) was down slightly from its modest bow. A repeat of ”CSI: Miami” capped the night (1.2/3 in 18-49, 5.2 million viewers overall).

Fox ran a close second to CBS on the night among adults 18-49, getting good production from repeats of ”The Simpsons” (1.6/5 in 18-49, 3.6 million viewers overall), ”The Cleveland Show” (1.6/5 in 18-49, 3.3 million viewers overall), ”Family Guy” (2.1/6 in 18-49, 4.2 million viewers overall) and ”American Dad” (1.8/5 in 18-49, 3.7 million viewers overall).
